Sharon Stone's PETA scan

Animal rights group PETA are determined to discover why Sharon "demonstrates a lack of empathy" towards animals by wearing fur, and so have written her a letter telling her they would be willing to pay for the scientific scan.

The letter reads: "Scientific studies suggest that the prefrontal regions of the brains of people who lack empathy might be underdeveloped. Here's our offer - would you allow PETA to pay for a scan of the prefrontal region of your brain to determine if comments and actions that seem to demonstrate a lack of empathy are the result of a physical defect?

"We urge you to undergo this test at our expense. With help, you might be able to develop empathy and curb your urge to scoff at various forms of misery and violence."

PETA (People for the Ethical Treatment of Animals) also blasted the 'Basic Instinct' actress for the comments she made about the devastating earthquake in China earlier this year.

Sharon sparked outrage when she described the natural disaster as "karma" for the way the country was treating neighbouring Tibet.

The letter continues: "Given that millions of people - including children - were killed, injured, and left homeless by the recent earthquake in China, everyone was shocked to hear you dismiss the devastating effects of this disaster.

"However, your cavalier attitude did not come as a surprise to us. We are used to the indifference that you flaunt and the callous remarks that you make about the suffering and death of the animals whose fur you wear so often."
